Other people playing games: "Nice graphics!"
Me playing games: "Wonder how they did that shader..."

Okay maybe that one shader variable was important after all...

Loneliness is when you implement a compute shader in Unity to render real, user-defined fisheye in RT, and you have no one to share your excitement with.

Game devs: Let's make characters as photorealistic as possible.

Some asian girls: Let's try to look as unrealistic as possible:

I had a project where I completely suprised the client and the company within the beginning. It was silky smooth, working on multiplatform ios android,standalone. I wrote the most complex shader I ever made. Everything was great and I even got a bonus for the project.
Then one day. Videos started to stutter. Not playing, completely black on some cases and some devices.
I started to think about reasons. I tried every solution I come up with. No success.
Updated all the codecs, middleware still nothing. Tried to solve the problem for a week. It was a total diaaster and I even thought I a dont deserve to be a developer.

We encoded the videos a few times. Decided to export the original video again, boom! It worked. Theres no particular reason why it worked. But it worked. I guess I am a good developer. Not the best but, eh.

It is 4:55.
I should sleep.
I've just created a GLSL shader on my phone which renders the Mandelbrot set in 4 bright flashing colors while zooming in.

Writing an efficient, modern renderer is truly an exercise of patience. You have a good idea? Hah, fuck you, GPUs don't support that. Okay but what if I try to use this advanced feature? Eh, probably not going to support exactly what you would like to do. Okay fuck it I'm gonna use the most obscure features possible. Congratulations, it doesn't work even on the niche hardware that supports that extension

If I sound jaded, ya better believe I f*cking am! I cannot wait for more graphics cards to support features like mesh shaders so we can finally compute shader all the things and do things the way we want to god dammit

Apparently "in" and "out" are the new "varying" and "attribute" in OpenGL's shader language...

Even buying a new graphics card can f*ck up your whole day! 😥

So I'm struggling to finish this library which among other things is supposed to write flowing text. And this one's taking foreeeever and I'm hating it so much already.

I just keep daydreaming of starting a "simple" platformer. And then I go, "hm the parallax must be nice, it needs to have as many layers as possible, oh and look at this video, here they're even zooming and each layer rescales differently, good effect, I need to add that too. Also a plain platformer is just boring, it needs to have adventure elements, and even RPG too, yeah why not. Hm, it needs to have some motion blur, but oh I need this 1/48 shutter speed to make it look cinematic. Okay how do I go about adding this blur effect? What? Libgdx doesn't provide one out of the box? I need to use opengl shaders? A shader, eh... I'm not even sure what that is. Okay, let's see how to do it. Wow that's a total mess and resource hungry, and how will I calculate it all as to make it match the 1/48 thing?"

You know... Simple. And in the end, I'll abandon the library and won't get anywhere with the platformer (as usual).

Tsk tsk tsk

Everytime you use OpenGL in a brand new project you have to go through the ceremonial blindfolded obstacle course that is getting the first damn triangle to show up. Is the shader code right? Did I forget to check an error on this buffer upload? Is my texture incomplete? Am I bad at matrix math? (Spoiler alert: usually yes) Did I not GL enable something? Is my context setup wrong? Did Nvidia release drivers that grep for my window title and refuse to display any geometry in it?

Oh. Needed to glViewport. OK.

Putting every file, even SHADER CACHES (that huge cyan flower here (this illustration was made with "gource"), yes, every of those tiny little dots is a file) or even complete libraries into their git repository.

Saw the moebius art style shader, implemented in webgl, I’m a god

I've been working on a shader for the past few days. Lots of doing math on paper and switching to code to implement it. Yesterday after 3 or 4 hours of trying to figure out why nothing is rendering, I realized that I wrote all my * for multiplication as x. Visual Studio never let me know its a syntax error, and my fried brain saw no issue. Needless to saw my shader is still bugged to hell, but at least my multiplication works.

Google: "shader particle trail effect"
Click the YouTube link
4 hours later... I've seen all the "gold digger prank" videos.
Disaster!

I swear both gl_PrimitiveID and the noiseX functions don't fucking work. No reason at all, they just don't want to work. Attached is a screenshot with a """""random""""" shade of blue per vertex (with flat interpolation) based on screen pos

So, in opengl 4.x, there are no primitives for circle, and the only ways to draw an almost perfect circle are following

Draw a triangle fan and fk up your memory for a circle
Draw a rectangle and use the fragment shader and distance equation to discard the bit that is not used
But you will need to add an if statement and potentially increase the frame time (from what i have heard)
And it will be more complicated than just using a triangle fan

There's nothing quite like an app force closing for no apparent reason, and no error log info.

Just spent an hour figuring out that one of the device I test on doesn't like linking GLSL shader programs if it contains a loop even know every other devices I've tested on are totally fine with it. 😑

Is it a good idea to switch from learning openGL to learning Vulkan now?
I was learning openGL in the past months and now that Vulkan is out I am thinking about learning that instead. I've heard that it's harder to learn though, so roughly how long do you think it would take to learn it as a openGL novice?
In openGL I have used instanced rendering with different textures, specular maps in the shader all in perspective 3D of course.

New to dr. And love so many story here.
Currently work on shader project which i hate and very bad at.
Anyone know good place to l arn different type of shader? I have some badic knowledge how glsl work. But not enough knowledge on how to make cool stuff.
Also trying to add the texture. Not work yet tho ;(

So, some friends of mine are going to work on a horror game in Unity2019.

Does anybody have software recommendations for audio editing, shader development or such?

Any advice greatly appreciated.

I was looking through some shader videos and wanted to see how hard it is to write one, and after some research I am now confused.

Are shades just basically fancy filters like black and white filters and those shitty Snapchat colour filters or is there a particular trait with shaders that diffferes them from filters that I am missing?

I always thought that shaders were all about ray tracing/marching and obtaining the effects that way.

Why is there no language that can run on a GPU, not considering GLSL and the such as they're shader languages and are only used for that.

Not finding what I want via google so I'll ask here: What's the deal with opengles android shaders freezing my phone's screen?
Is it normal unavoidable behaviour for a shader with an infinite loop to fuck up the visual output irreversibly (until phone restart)?

Sophomore year starting soon so I'm looking for new project (s) to complete in parallel with the studies.
Some are more design-y and some more backend-y but I recently started getting better at designing so :)

1) Learn some fragment shader stuff. I've always been messing around with graphics and have a game on steam, so I think that's a good idea to be paired with signal processing.

2) Reactive web services. Preferably with spring-boot or vert.x but

3) I would also like to dive into golang (and make some reactive thing with it)

4) WebAssembly seems nice... But I got some concerns

5) exercise making wireframes -> CSS (with some js)

6) I've never really done any real backed work with nodejs, except serving and aot compiling js, or doing gulp tasks

7) Implementing a whole project, or a fraction of it as serverless on aws

* I'm definitely going to use a couple very simple services to make a docker swarm with load balancing, etc, just because I know how everything works but got no practical knowledge

8) Design an esports jersey for the university department I'm in (shouldn't take long)

So what do you guys think? Recommendations are welcome :)
